[0002] Heating furnaces are used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry and pharmaceuticals. In the metallurgical industry, heating furnaces are equipment that heat materials or workpieces (usually metals) to rolling and forging temperatures.

[0003] An existing safe and durable heating furnace for metal smelting (authorization announcement number CN213515029U) has the following defects: the above-mentioned device protects the inside and outside of the heating furnace through an outer protective layer, an inner protective layer, an anti-corrosion layer, an anti-rust layer, an insulation layer and a heat-resistant layer, so as to improve the durability of the heating furnace. However, during long-term use, metal materials are continuously put into the heating furnace for heating. During the putting process, the metal materials are easily collided with the coating, causing damage to the coating. Long-term use can easily reduce the durability of the heating furnace, thereby reducing the service life of the heating furnace. For this reason, we propose the utility model. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 A safe and durable heating furnace for metal smelting comprises a bottom plate 1, a furnace body 2 is arranged on the top surface of the bottom plate 1, a heating structure is arranged inside the furnace body 2, a protective structure is arranged inside the furnace body 2, the protective structure comprises a heat insulation layer 3 fixed to the inner wall of the furnace body 2, a corrosion-resistant layer 301 is fixed on one side of the heat insulation layer 3, support plates 302 are rotatably arranged on both sides of the furnace body 2, the support plates 302 are fixed to the bottom surface of the bottom plate 1, a distance is left between the bottom surface of the furnace body 2 and the bottom plate 1, the heat insulation layer 3 is high-temperature resistant ceramic fiber, and the corrosion-resistant layer 301 is made of stainless steel.

[0022] In the embodiment, the heating structure includes a heating crucible 201 fixed inside the furnace body 2, the outer circular wall of the heating crucible 201 is wound with a coil 202, and a gap is left between the outer circular wall of the heating crucible 201 and the inner circular wall of the furnace body 2. The heating crucible 201 is a prior art. Through the setting of the protective structure and the heating structure, the staff puts the metal material into the heating crucible 201, energizes the coil 202, and utilizes the principle of electromagnetic induction to make the coil 202 heat the heating crucible 201 at its center, and the metal material in the heating crucible 201 melts at high temperature. During the heating process, the corrosion-resistant layer 301 prevents the high-temperature gas generated during the heating process from damaging the furnace body 2, and the thermal insulation layer 3 prevents the heat loss in the furnace body 2. There is a gap between the heating crucible 201 and the inner wall of the furnace body 2, and the heat is concentrated at its center when the coil 202 is heated, which reduces the damage of the inner wall of the furnace body 2 caused by high temperature. At the same time, the bottom surface of the furnace body 2 is suspended above the bottom plate 1, which reduces the wear of the outer wall of the furnace body 2, thereby improving the safety and durability of the heating furnace.

[0023] In the embodiment, a mounting block 4 is fixed to the outer wall of the furnace body 2, and two connecting ropes 401 are fixed to the bottom surface of the mounting block 4. The connecting ropes 401 are steel ropes. An electric push rod 402 is provided on the top surface of the bottom plate 1. The bottom ends of the two connecting ropes 401 are fixed to the telescopic ends of the electric push rod 402. When the heating of the metal material is completed, the staff can start the electric push rod 402 to extend so that the connecting rope 401 pulls one side of the furnace body 2. The furnace body 2 is tilted under the action of the support plate 302, so that the molten metal material in the furnace body 2 is poured into the relevant container, thereby eliminating the need for staff to participate in the unloading work, further improving the safety of the heating furnace.

[0024] In the embodiment, a placing table 5 is fixed to one side of the base plate 1, one end of the electric push rod 402 is fixed to one side of the placing table 5, and a plurality of limiting bars 501 are fixed to the top surface of the placing table 5. When pouring molten metal materials, the staff can place the container on the placing table 5, and the limiting bars 501 limit the container to prevent the container from shifting during the pouring process.

[0025] In the embodiment, two limit plates 6 are fixed to the outer circular wall of the furnace body 2, and the limit plates 6 are U-shaped. The two connecting ropes 401 are slidably inserted into the two limit plates 6 respectively. When the connecting rope 401 pulls the furnace body 2, the limit plates 6 limit the connecting rope 401 to prevent the connecting rope 401 from moving and deviating.

[0026] In the embodiment, a mounting cover 7 is attached to the top surface of the furnace body 2, and an exhaust hole is opened on the top surface of the mounting cover 7. When the metal material is melted, the mounting cover 7 can prevent the molten metal from splashing out of the furnace body 2, thereby improving safety.

[0027] Working principle: During use, the staff puts the metal material into the heating crucible 201 in the furnace body 2, closes the installation cover 7, and then energizes the coil 202. Using the principle of electromagnetic induction, the coil 202 heats the heating crucible 201 at its center, and the metal material in the heating crucible 201 melts at high temperature. During the heating process, the corrosion-resistant layer 301 prevents the high-temperature gas generated during the heating process from damaging the furnace body 2, and the heat-insulating layer 3 prevents the heat in the furnace body 2 from being lost. There is a distance between the heating crucible 201 and the inner wall of the furnace body 2, and the heat is concentrated in the center of the coil 202 when it is heated, which reduces the damage of the high temperature to the inner wall of the furnace body 2. When the metal material is heated, the staff removes the installation cover. 7. Start the electric push rod 402 to extend, so that the connecting rope 401 pulls one side of the furnace body 2. The furnace body 2 is tilted under the action of the support plate 302, so that the molten metal material in the furnace body 2 is poured into the relevant container, so that there is no need for staff to participate in the unloading work. When pouring the molten metal material, the staff can place the container on the placement table 5, and the limit bar 501 limits the container to prevent the container from shifting during the pouring process. When the connecting rope 401 pulls the furnace body 2, the limit plate 6 limits the connecting rope 401 to prevent the connecting rope 401 from moving and shifting. When the metal material is melted, the installation cover 7 can prevent the molten metal from splashing out of the furnace body 2, thereby improving safety.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
